We have developed our own projects and advised a number of major energy companies, both in the UK and Europe.
In terms of conceptual design, px group has developed a 1020 MW CHP scheme on Teesside, UK (Thor Cogeneration Ltd). This project is Greenfield and consideration has been given to all areas of design including general site, gas turbines, steam turbines, heat recovery steam generators, cooling systems, export capacities and site services in order to meet the project requirements.
In particular, the group has considered areas such as:
- Liaison with OEMs for best fits
- Operating flexibility i.e. baseload, part-load, two shifting, peaking
- HRSG selection – conventional versus once through
- Cooling Tower – wet versus dry
- Fuel flexibility i.e. fuel spiking
- Integration of customers steam requirements
- Reliability and availability
- Redundancy for maintaining steam supplies
- Operating efficiencies
- Environmental requirements
- Compliance with Grid Operator requirements
The project received Section 36 consent in August 2008 and was sold to a major utility company in November 2008.
Our team has extensive experience in developing feasibility and FEED studies for an array of international clients across the spectrum of industry.
The main commercial purpose of a feasibility study is to evaluate the economic viability of the proposed project and answer the question: “Does the idea make economic sense?”
The study should investigate the business opportunity, including investigation of all the difficulties and risks that may stand in the way of the project’s success.
The conclusion of the feasibility study will indicate whether or not to proceed with the proposed project.
If the results of the feasibility study are positive, then the next stage would be to undertake a FEED study.
A feasibility study examines three main areas:
- Market (internal/external)
- Technical and organisational
front end engineering & design
A Front End Engineering & Design (FEED) study is a vital starting point for any development.
px group has the expertise and resources to help our clients at every stage of the process.
Coming after the feasibility study, the FEED focuses on the key technical requirements of the project as well as high level investment costs and is used as the basis for developing the detailed design and EPC tender packages.
We understand the importance of this critical stage in project development and ensure that the study reflects clients’ specific requirements by maintaining close communication throughout the duration of the study.
reliability & maintainability
Central to a design review of this type is the production of a Reliability, Availability and Maintainability (RAM) study.
The RAM study sets out to ensure that the facility being modelled will achieve its designed (or target) availability.
A typical RAM study will investigate the major process units and take account of redundancy, planned and unplanned shut downs.
The RAM study will aim to identify the probability that an asset will fail and, upon failure, how long it will take to repair. The benefits of undertaking such as study include:
- Estimation, prediction and confirmation of future production performance against the target
- Indentification of critical loss contributors in order to make informed design improvement decisions
- Indentification of malfunctioning/poor standard equipment by comparison with predictions
- Provision of valuable information to determine the correct maintenance strategies and philosophies
px group designs, engineers and manages projects across the whole range of engineering sectors.
We have the flexibility and the strength to be able to deliver large or small projects successfully anywhere in the world.
The engineering disciplines we cover include:
- Process engineering
- Piping engineering
- Mechanical engineering
- Material handling
- Instrument and control engineering
- Electrical engineering
- Civil and structural engineering
- Building services
All px design, engineering, procurement, construction and commissioning activities are controlled under an ISO 9001:2008 accredited Quality Management System (QMS). This assures all client’s that we will deliver exactly what is required, on time, on budget and to an appropriate quality.
Our QMS is available to all its personnel, whether at head office or on site, via the intranet and this on-line access guarantees up-to-date standards and procedures are accessible throughout the distributed organisation.
We take pride in the quality of the work it undertakes as evidenced by their investment in developing and implementing the QMS.
